| 摘 要： | 利用生物还原法制备纳米银溶胶，借助于UV-Vis表征技术对其热稳定性和化学稳定性进行考察。结果表明：生物法制备的纳米银溶胶在100 ℃下加热6 h，UV-Vis谱图未发生明显变化；H＋和具有高价阳离子的电解质对其稳定性的影响明显；OH－对银溶胶的稳定性影响相对较弱。生物法制备的纳米银溶胶在热稳定性、化学稳定性方面均略优于柠檬酸三钠法制得的银溶胶

| Abstract: | The thermal and chemical stabilities of the colloid silver nanoparticles prepared by bioreduction were investigated in virtue of UV-Vis spectrometer. The results indicate that UV-Vis spectra of silver colloid prepared by bioreduction have not significant change after heat treatment at 100 oC for 6 h. Hydrogen ion and the electrolyte with multivalent cation markedly influence stabilities of the silver colloid, while hydroxide anion has a weak influence on its stability. Thermal and chemical stabilities of the silver colloid prepared by bioreduction are superior to that of the silver colloid prepared by the sodium citrate reduction method |
